Results and Discussion
The characteristics of the samples of students from the four countries are
presented in Table 2. There appears to be several exceptions to the general demographic
pattern. For example, there were disproportionately more males in the
sample from Chile; Swiss students described themselves to be more liberal, and
students in England tended to be politically middle-of-the-road. Those differences
did not seem to present problems with the survey results.
Environmental knowledge
A Kruskal-Wallis H test indicated that the sample populations were different
in terms of knowledge (df = 3; p < 0.01).ADunnett C post hoc analysis suggested
a significant difference between the knowledge scores of students from Chile in
comparison with students from the other three countries. These statistics indicate
that students from Chile were less knowledgeable on the 20 questions used
for the survey than students from England, Switzerland and the United States
who responded (Table 3). The scores on the knowledge section of the survey for
students from the United States were significantly different from the scores from
students from Switzerland and England. The researcher concluded that students
from the United States were less knowledgeable on the 20 survey questions than
studentswhoresponded to the survey from England and Switzerland.Nosignificant
differences in knowledge scores were observed between the students from
England and Switzerland.
